Description.

Body length of female: 7.31 mm (n = 1). Color of A1: yellow to orange. A6 in female: distinctly wider than long. A5 in female: as long as wide. Number of basiconic sensilla on A7: 1. Number of basiconic sensilla on A12: 1. Sculpture of dorsal A1: punctate; smooth. Color of head: black. Sculpture of frons directly above interantennal process: areolate. Central keel: present only in ventral portion of frons. Ventral margin of clypeus: straight. Granulate microsculpture of dorsal frons: absent. Occipital carina: complete. Granulate microsculpture of vertex: absent. Sculpture of occiput: smooth. Sculpture of gena: narrowly smooth ventrally, punctate rugose dorsally.

Color of mesosoma: variably orange to black. Sculpture of epicoxal lobe posterior of propleural epicoxal sulcus: sparsely punctate. Sculpture of lateral pronotal area above pronotal cervical sulcus: smooth dorsally, rugose ventrally. Sculpture of netrion: transversely striate. Microsculpture of mesoscutum: absent. Macrosculpture of mesoscutal midlobe: sparsely punctate at anterior margin, smooth posteriorly. Macrosculpture of lateral lobe of mesoscutum: smooth. Sculpture of notaulus: foveate. Notaular foveae: interconnected. Median mesoscutal carina: present anteriorly, not extending to posterior margin of mesoscutum. Shape of mesoscutellum: strongly transverse. Mesoscutellum in lateral view: flat. Sculpture of mesoscutellum: smooth throughout. Shape of metascutellum: trapezoidal with broad posterior margin. Median metascutellar carina: absent or indistinguishable from sculpture. Sculpture of metascutellum: areolate. Sculpture of lateral propodeal area: rugose. Mesopleural carina: present. Sculpture of mesepisternum below femoral depression: largely smooth, punctate rugose anteriorly and directly below femoral depression. Sculpture of dorsal metapleural area: rugose. Setation of dorsal metapleural area: absent. Setation of area directly dorsal to the metapleural triangle: absent. Sculpture of ventral metapleural area: rugose throughout. Color of legs: orange yellow with coxae dark brown. Length of hind basitarsus: distinctly longer than remaining segments combined. Sculpture of hind coxa: densely punctate.

Length of postmarginal vein: approximately as long as stigmal vein.

Color of metasoma in female: black. Horn on T1 in female: present. Striae of posterior margin of T1 in female: dense. Transverse sulcus on T2: present. Sculpture of T2: densely longitudinally striate, punctate rugulose in interstices, with a narrow smooth strip medially. Sculpture of T6 in female: densely longitudinally striate, with fine punctures in interstices. Length of T6 in female: at least 1.5 × longer than wide. Shape of T6 in female in lateral view: flat. Apical spine on female T6: absent. Sculpture of medial S2: punctate rugose, with a narrow smooth strip medially.

Diagnosis.

This species can be easily distinguished by the following characters: body extremely elongate, central keel present only in ventral portion of frons, mesoscutellum strongly transverse, and T2-T6 with with a narrow smooth strip medially.

Etymology.

The epithet is inspired by the Latin word for flat or plain, in reference to the flat and smooth mesoscutellum, and is intended to be treated as an adjective.
